By being sandwiched between the 23B and 23B, the cable is held in a state of being extended in the front-rear direction and in a state of being bent in the vertical direction. As a result, the terminal 12 can firmly hold the core wire 13 (see FIG. 10).

Next, when the rear holder 31 is pressed forward, the lock receiving portion 38 of the rear holder 31 rides on the main locking lock portion 37 of the housing 30 and elastically deforms. Further, when the rear holder 31 is pressed forward, the main locking lock portion 37 and the lock receiving portion 38 are locked. Further, the partition wall 34 of the housing 30 is fitted between the pair of protruding

walls

42A and 42B of the rear holder 31. As a result, the rear holder 31 is held at the main locking position with respect to the housing 30 (see FIG. 10).

Finally, by accommodating the housing 30 and the rear holder 31 in the cover 48, the assembly of the connector 10 is completed (see FIG. 1).
